DEVICE FOR SHARPENING HORSESHOE-CALKS.

SPECIFICATION forming part of Letters Patent No. 250,482, dated December 6, 1881.

Application filed October 10, 1881. (Model.)

To all whom it may concern Be it known that I, HIRAM BAKER, a citizen of the United States of America, residing at Coldwater, in the county of Branch and State of Michigan, have invented certain new and useful Improvementsin SharpeningHorseshoe- Ualks without Removing the Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to devices for sharpening horseshoe-(talks, and it consists ofthe construction and arrangement of its several parts, as Will be hereinafter fully set forth.

In the accompanying drawings, Figure l is a plan view of my invention; Fig. 2, a Vertical section, and Fig. 3 a view of the slide.

A is the iron frame in which is inclosed the operating mechanism. It is provided with a cross-bar, a, as shown.

Placed in elongated holes in the sides ofthe frame is the round iile B. Upon one ofits ends is secured the gear-wheel b, which engages with the gear-wheel b', pivoted in the projection a', and has secured to it ashaft running through it to the crank b2, by which the leis rotated.

Placed within the frame is the spring-frame C. lts ends are bent at right angles to its length, and have slots in their ends, which embrace and have bearing upon the journal-shaft of the le B. It has the rod c attached to it, which operates through a hole in the top of the frame.

Placed around the rod is the spiral spring c', as shown.

Operating in grooves in the sides of the frame is the slide D. It is provided with recesses in its ends to preventinterference with the springframe C, and is adjusted in any desired position by the thumb-screw d, which operates through the cross-bar a, and in a cup-shaped disk, d', in the slide D, as shown.

In the operation ot' my device the horses hoof, with shoe attached, is held between the knees of the artisan, and the machine applied to the bottom ofthe shoe, the calks to be sharpened entering the recess between the tile and bottom of the frame A. In sharpening the toecalk the machine is placed on the hoof with the tile end toward the toe of the shoe, and the calk is placed in the recessindicated. In sharpenin g the heel-calks the position of the machine is reversed, the file end being turned toward the heel and the'heel-calks entered within the recess, as set forth. The tile is then revolved, andthecalks will be sharpened bycoutactwith it. During the operation the machine is held in position by the hand.

1n the operation of the machine the bottom of the horseshoe rests upon the slide D, and the calk extends into the recess between the file and frame A. It will be seen that by raising or lowering the slide the calk will be raised or lowered upon the file, as desired. In sharpeniug long calks the slide is raised a sufticient distance to bring the end of the calk against the tile, and when short calks are to be sharpened the slide is lowered to the proper distance above the le.

In combination with the frame A and gearwheel b', the Jdie B, provided with gear-wheel b, spring-frame C, spring c', and adjustable slide D, all arranged and operatin g as set forth.

In testimony whereof Iaffix my signature in presence of two Witnesses.

HIRAM BAKER.
